There wasn't a discussion though, it was just everyone telling the other group how stupid they were...

When both sides have their minds made up and are not willing to budge or compromise on their position, what's the point?

That's a shame that you stopped reading I think some interesting points have been made along the way. And you're quite wrong about the second part one side has completely made up their mind. The other has decided their mind based on what their current understanding and what proof their is and will change it overnight if there anyone can produce credible proof that it is wrong.
